SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 237,164, dated February1, 1881.

Application `filed December 2, 1880. (Model.)

To all whom t may concern:

Be it known that I HIRAM C. BRUNER, of Lansdale, county of Montgomery,and State of Pennsylvania, have invented an Improve ment in Window-SashLocks, of which the following is a specication.

My invention relates to sash-locks for windows, but is more particularlydesigned to replace the balance-weights and their cords and boxes; andit consists in a notched arm or shaft free to be oscillated or rotated,and secured to the upper sash-frame, said bar working through aguide-box secured to the lower sash frame, and provided with two pawlswhich operate in opposite directions; further, in securing to thewindow-frame proper a slotted plate in which a bent end at the top ofthe bar works, all of which mechanism is more fully set forth in thefollowing specication, shown in the accompanying drawings, and referredto in the appended claims.

In the drawings, Figure 1 is a perspective View of a window embodying init my invention. Fig. 2 is a front elevation of same, showing lower sashheld up. Fig. 3 is also a front elevation, showing both sashes lockedwhen the window is closed. Fig. 4 is an enlarged perspective view ofpawl, lock, and rod.

A lowed oscillating or rotating movement in a The operation is asfollows: To lock the window, let the lower sash, C, down to its lowestposition; then turn the arm Gr to the right to aposition parallel to thewindow, then raiseit up, which action also raises the upper sash, B, andthe arm F will pass through slot M in plate L then turn the arrn G to aposition perpendicular to the window, and the pawl K drops into thelowest notch E in the bar D, and the upper sash will be locked by theplate L and the lower sash by the pawl K. This is shown in Fig. A3. Toraise the lower sash, turn the arm Gr to the left until parallel to thewindow Vthen raise the sash C to any height desired, and the weightedpawl J, catching in the notches E of bar D, prevents the sash fromdescending, as shown in Fig. 2. To lowei` the upper sash, let the lowersash be down; then turn the arm G to the right untilparallel to thewindow; then lower to the desired position, and then turn the arm to aposition perpendicular to the window, and the pawl K will lock itin thatposition by engaging a notch, E, as shown in Fig. 1. To raise the lowersash and lower the upper sash for ventilation, turn the arm Gperpendicular to the window and raise the lower sash to any desiredheight; then secure it there by the cam lock or catch N 5 then performthe operation described above to lower the upper sash, and both theupper and lower windows are opened. v

lf desired, the notches and pawls may be dispensed with and camfriction-catches used.

Sash-locks have been made in which a rod has been hinged to the upperpart of the upper sash and provided with a hole in the lower end, which,when both window sashes were closed, fitted over a pin in the lowersash, and the weight boxes, cords, and weights were used; hence theupper window-sash could be raised or lowered by pushing or pulling onthe rod, and the windows could be locked when closed, and then only.Sash-locks have also been made i n which a notched rod was rigidly fixedin the window-frame and the windows provided with spring-catches, whichcaught in the notches and supported the window-sashcs in any desiredposition; but neither of these is as good as mine, and both. are veryimperfeet.

The object ot' my invention is to dispense IOO with the expensiveweight-boxes, the weights, their cords, and sash-locks, and substitutetherefor a simple device which will perform the same function at a muchreduced cost.

I am aware of the patent to Danforth, No. 89,205, and do not claimanything therein shown and described.

Having now described my invention, WhatI claim as new, and desire tosecure by Letters Patent, is-

1. A window-sash lock consisting ot' a rod oscillating or rotating in afixed bearing secured to the upper sash, and at the bottom slidingthrough a box or bearing secured to the lower sash, in combination withmechanism on the lower sash to lock said rod in its highest, lowest, orany intermediate position, substantially as and for the purpose specied.

2. In a Window-sash lock, a rod oscillating or rotating in a xed bearingsecured to the upper sash, provided with mechanism to lock it to the topof the Window-frame and mechanism to lock it in any position to thelower sash,I substantially as and for the purpose specified.

3. In a window-sash lock, the combination of notched bar D, oscillatingor rotating in a fixed bearing secured to the upper sash, B, andprovided with arm F, slotted plate L, secured to the top of thewindow-frame, box I, secured to the lower sash, O, to guide the bar D,and provided with pawls J K, or their equivalent, Workingin oppositedirections, substantially as and for the purpose specified.

4. In a window-sash lock, the combination ot' bar D, secured to theupper sash, B, by a bearing, and capable of oscillating or rotatingtherein, arm F, and slotted plate L, secured to the top of thewindow-frame A, substantially as and for the purpose specified.

5. In a window-sash lock, the combination of upper sash, B, lower sash,C, rod D, secured to the sash B by a bearing, and capable of oscillatingor rotating therein, and provided with notches E, guide-box I, and pawlsJ and K, which work; in opposite directions, substantially as and forthe purpose specitied.

In testimony of which invention I hereunto set my hand.
